AS396190 LEASEWEB-USA-SEAASN lookup: IP ranges, prefixes and network type
AS396190 is the autonomous system number (ASN) announced by LEASEWEB-USA-SEA. It announces 81 prefixes, 121,600 IPv4 addresses in total. Every address inside those ranges is routed by this operator, which is what makes the number the shortest answer to who runs a given address.
Directory data is unavailable at the moment, so the prefix list and the range membership counts are missing from this page. What you can see comes from the committed snapshot and is accurate as far as it goes. Try again shortly.

What AS396190 means for detection
Addresses on LEASEWEB-USA-SEA are infrastructure: servers, containers and managed services, not people at home. Our engine classifies them datacenter or hosting and never as VPN, because renting a machine is not anonymising traffic. That distinction matters for what you do next. A signup from here is worth a second look because automation lives on networks like this one, but blocking the range outright also blocks every monitoring service, payment webhook and corporate proxy that runs on it.
The verdict for a single address is never settled by the ASN alone. It is the starting point, and IP Detection adds range membership, behaviour and history on top of it before it answers.
